Harmonicon
A toy instrument with free reeds, blown by the mouth.
Harmonics, Overtones, Partial Tones. (I) The sounds produced by the division of a vibrating body into equal parts; it is upon the presence or absence and relative intensity of the overtones that the quality of the sound depends. Open pipes, strings, brass instruments, and instruments with double reed (bassoon and hautboy) give the following series :- C generator 1 2 3 4 5 6 7 8 9 C G C E G B2 C D E, etc. 1 111 2 345 6 7 1 1 1 8 9 10 Closed pipes and beating reeds (clarionet) Habeneck, F.

HARMONIUM omit all the even numbers in this series. (2) The sounds produced on the violin by touching the string lightly at one of the points of division; those produced by thus touching the open string are called natural harmonics. Artificial harmonics are produced by stopping the string with the first finger and touching it lightly with the fourth, at the interval of a fourth above; the resulting harmonic is two octaves above the stopped note. In writing music this is indicated by writing thus :- Played. -6 Effect.
The lozenge-shaped notes indicate the notes to be lightly touched. Natural harmonics are frequently used on the harp, guitar, and mandolin.
